Specification of Letters Patent.

Patented Apr. 1, 1919.

Application filed June 22, 1918. Serial No. 241,407.

To all whom it may concern.

Be it known that I, WILLIAM J. B nsr, a citizen of the United States, and residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and Improved Hydrocarbon-Burner, of which the following is a specification.

This invention relates to burners for alcohol and the heavier liquid hydro-carbons such as kerosene, and its object is to provide a burner which will operate with a nunimum of odor and produce a maximum of heat for the amount of fuel consumed. I

This invention consists in the details of construction shown in the accompanying drawing and particularly pointed out in the.

claims.

The burner is shown to be made up of an inner chimney, an outer chimney, a vaporizcr and a cowl. The inner chimney 1, is preferably cylindrical and provided with an imperforate top 2, a diaphragm 3 and with a centering ring 4 at its lower end to position it on the vaporizer. The inner chimney and diaphragm are perforated to permit air to pass freely. The outer chimney 5 rests upon a shelf 6 formed on the upper edge of the outer side 7 of the vaporizer and the'centering ring rests on the upper edge of the inner side 8. The width of the bottom 9 of the vaporizer is preferably sufficient to permit the wick 1O resting on this bottom to be substantially below the bead or rib 12 formed on the ring 4. The two sides 7 and 8 are perforated and are integral with the bottom. A fuel pipe 13 connects into this vaporizer and the cowl 14 may be supported b Y the crossed rods 15 extending through the chimneys. V v

\Vhen the burner is to be used, fuel is permitted to flow into the bottom of the vaporizcr and a small wad of asbestos on the end.

of a wire is lowered down between the chimneys and dipped into the fuel, after which it is lifted out, ignited. and again lowered to ignite the wick 10. Because of the bead 12, the wire will not engage the wick and injure it. The resulting flame will receive air through the holes in the sides 7 and 8, and as these are integral with the bottom 9, the entire va orizer soon becomes very hot, and the fue becomes vaporized and burns between the sides of the vaporizer and between the chimneys, sufiicient air entering through the holes in the sides of the vaporizer and in the-chimneys to produce complete combus tion and therefore a clear blue flame.

It has been found that the small amount of paraffin which is carried by most of the kerosenes on the American market is deposited in the bottom and against the lower part of the sides of the Vaporizers now in the market. This deposit is very small on the inner side when such side is made inte gral with the innerchimney, as my former Patent No. 1,177,297, dated March 28, 1916, but in that case, the paraflin is deposited at the lower edge of the outer side of the outer chimney. This coating acts like a wick in that it serves as a vehicle for the fuel which creeps up thereon or therein and evaporates on the upper surface thereof, producing a disagreeable odor. While a, slmilar deposit occurs on the inner side of the outer chimney, the result is not so objectionable.

By forming the vaporizer with both sides and bottom mtegral; and both sides per forated so as to insure combustion between the sides, these sides get so hot that there is no deposit of parafiin where the sides of the vaporizer ioi'n the lower edges of the chim-" neys and ere is therefore no escape of fuel vapor into the atmosphere at thosepoints. The combustionlof thefuel seems to be more perfect when highly heated in'the vaporizer and the odor of the burner is reduced to a minimum.

Sizes and proportions of this vaporizer may be changed within quite wide limits without departing from the spirit of my invention as set forth in the following claims.

I claim l. A burner having concentric perforated.

outer and inner Ichimneys, a vaporizer integral with the lower ends of both outer and inner chimneys and in the form of a trough,

and a fuel supply pipe connecting into the vaporizer.

2. A burner having concentric perforated outer and innerchimneys in sectlons, a vaporizer below the chimneys comprising a trough with which the lower sections of the chimneys are integral, and a fuel supply pipe connecting into the outer side of the vaporizer, the inner side of the vaporizer being of less diameter than upper end of the 1 inner chimney, a supporting ring mounted upon the upper edge of the ower section of the inner sld-e to support the inner chimney, and awick resting upon the bottom of the vaporizer and fitting .ag'sfgnst the inner wall thereof.

3. A burner having perforated outer and inner chimneys insections, a vaporizer be- -5 low the chimneys and integral with the lower ends of both'of them, a; wick resting upon the bottom of the vaporizer, the inner side of the vaporizer being of less diameter than the upper end of theinner chimney, and a support ring mounted upon the upper 10 edge of the section of 'the inner chimney which is integral with the vaporizer to support the remainder of the inner chimney.
